Description

Technical Field

[0001] The utility model belongs to the field of architectural design, and more specifically, particularly relates to a foldable drawing table. Background Art

[0002] A drawing table is a table used in the fields of art creation and engineering drawing. Its main function is to post drawing paper and help draftsmen to complete drawing operations smoothly. At present, traditional drawing tables are mostly composed of four sets of fixed legs and a desktop with adjustable tilt angle. It can be seen that the overall structure of the traditional drawing table is rigid and fixed and occupies a large volume. If draftsmen need to carry out on-site drawing work in different locations, the drawing table cannot be carried along with the drawing tools, and on-site drawing work will be extremely inconvenient. In addition, since the desktop of the drawing table is mostly tilted, in order to prevent the drawing from sliding on the desktop, it is necessary to use a clip to clamp it on the edge of the desktop. If the size of the drawing is much smaller than the desktop area, the drawing will be posted on the edge of the desktop and cannot be placed in the center of the desktop, making the drawing operation of small drawings extremely inconvenient.

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figure 1-Figure 9As shown, the utility model provides a foldable drawing table, including a handle 15; the handle 15 is hinged on the left side of the drawing table body 8, and the handle 15 is hinged on the right side of the storage table 2; a universal caster 24 is installed on the left side of the storage table 2, a magnet block 25 is welded and connected to the right side of the storage table 2, an anti-slip pad 3 is bonded to the upper side of the storage table 2, a drawer 1 is installed on the front side of the storage table 2, a table leg frame 4 is hinged on the lower side of the storage table 2, and a foot pad 14 is bonded to the lower side of the table leg frame 4; it also includes a drawing table body 8, a splint 9, a connecting rod 12, a threaded folding rod 17, a threaded adjustment rod 21, a fixing plate 23 and a folding turntable 26; a guide rod 20 is welded inside the drawing table body 8, a universal caster 24 is installed on the right side of the drawing table body 8, a magnet block 25 is welded and connected to the left side of the drawing table body 8, and a drawing table body 8 is provided. It is hinged to the storage table 2, and the upper side surface of the drawing table body 8 is hinged with a drawing board 6, and the top end of the drawing board 6 is hinged with a lampshade 5, and an LED lamp tube 11 is installed inside the lampshade 5, and the LED lamp tube 11 is connected to the battery box 18 through a wire; the battery box 18 is connected to the rear side surface of the drawing board 6 by bolts; the rear side surface of the drawing board 6 is hinged with a supporting connecting rod 19, and the bottom end of the supporting connecting rod 19 is hinged to the upper side surface of the sliding frame 22; the top end of the connecting rod 12 is hinged to the lower side surface of the sliding block 16, and the bottom end of the connecting rod 12 is rotatably connected to the outer side surface of the supporting rod 13; the supporting rod 13 is welded to the table leg frame 4; the front end of the threaded adjustment rod 21 is installed with an adjustment knob 7; the folding turntable 26 is welded to the threaded folding rod 17; two groups of threaded through holes are provided on the fixing plate 23, and the clamping bolts 10 are screwed into the threaded through holes of the fixing plate 23.

[0025] When the utility model is folding and storing the drawing table, the folding turntable 26 is manually turned, and the folding turntable 26 drives the left threaded folding rod 17 to rotate. Since the storage table 2 and the drawing table body 8 are in the flipped and unfolded state, the protrusion of the left threaded folding rod 17 is inserted into the groove at the left end of the right threaded folding rod 17, and the left threaded folding rod 17 can drive the right threaded folding rod 17 to rotate synchronously. Since the two groups of threaded folding rods 17 are meshed and connected in the threaded through holes of the two groups of sliding blocks 16, the two groups of sliding blocks 16 will respectively pull the hinged two groups of connecting rods 12 to flip, and the two groups of connecting rods 12 will pull the two groups of table leg frames 4 to flip inward synchronously through the two groups of support rods 13, until the two groups of table leg frames 4 are flipped to the bottom of the drawing table body 8 and the storage table 2 respectively. Since the drawing table body 8 and the storage table 2 are hinged to each other, the drawing table body 8 and the storage table 2 can be mutually Flip and fold. When the drawing table body 8 and the storage table 2 are folded in half, the magnet block 25 welded to the drawing table body 8 and the magnet block 25 welded to the storage table 2 are opposite to each other, and the two groups of magnet blocks 25 attract each other to prevent the drawing table body 8 and the storage table 2 from flipping and separating, completing the folding and storage work of the drawing table. When the drawing table is clamping the drawings, the drawings are placed on the drawing board 6, and then the clamping plate 9 is slid along the two groups of through grooves of the drawing board 6 to the edge of the drawings, and then the clamping bolts 10 are screwed. Since the clamping bolts 10 are inserted into the through holes of the clamping plate 9 and the through grooves of the drawing board 6 in turn, the outer side surface of the clamping bolts 10 is threadedly screwed into the threaded through holes of the fixing plate 23, and the clamping bolts 10 clamp the clamping plate 9 and the fixing plate 23 on the drawing board 6. The clamping plate 9 presses the edge of the drawing and makes the drawing fit tightly against the upper side of the drawing board 6, completing the clamping and posting of the drawings.
